From f8cfa618dccbdc6dab5297f75779566a388a98fd Mon Sep 17 00:00:00 2001 From: Dominik Brodowski Date: Mon, 14 Nov 2005 21:25:51 +0100 Subject: [PATCH] pcmcia: unify attach, EVENT_CARD_INSERTION handlers into one probe callback Unify the EVENT_CARD_INSERTION and "attach" callbacks to one unified probe() callback. As all in-kernel drivers are changed to this new callback, there will be no temporary backwards-compatibility. Inside a probe() function, each driver _must_ set struct pcmcia_device *p_dev->instance and instance->handle correctly. With these patches, the basic driver interface for 16-bit PCMCIA drivers now has the classic four callbacks known also from other buses: int (*probe) (struct pcmcia_device *dev); void (*remove) (struct pcmcia_device *dev); int (*suspend) (struct pcmcia_device *dev); int (*resume) (struct pcmcia_device *dev); Signed-off-by: Dominik Brodowski --- drivers/mtd/maps/pcmciamtd.c | 54 ++++++++------------------------------------ 1 file changed, 9 insertions(+), 45 deletions(-) (limited to 'drivers/mtd/maps') diff --git a/drivers/mtd/maps/pcmciamtd.c b/drivers/mtd/maps/pcmciamtd.c index 93c05dfa030..f0f8916da7a 100644 --- a/drivers/mtd/maps/pcmciamtd.c +++ b/drivers/mtd/maps/pcmciamtd.c @@ -66,8 +66,6 @@ struct pcmciamtd_dev { }; -static dev_info_t dev_info = "pcmciamtd"; - /* Module parameters */ /* 2 = do 16-bit transfers, 1 = do 8-bit transfers */ @@ -708,30 +706,6 @@ static int pcmciamtd_resume(struct pcmcia_device *dev) return 0; } -/* The card status event handler.
